Answer:

Hot dog sold = 33

Sodas Sold = 72

Step-by-step explanation:

Given:

At a hockey game a vender sold a combined total of 105 sodas and hot dogs. The number of sodas sold was 39 more than the number of hot dogs sold

To Find:

Number of soda/hot dog sold

Solve:

h + ( 39 + h ) = 105

h + 39 + h = 105

2h + 39 = 105

h + 19.5 = 52.5

h = 52.5 - 19.5

This as a system does not use any inequality. "39 more than" means, +39.

h = 33 meaning d= 72

Add to check Answer:

33 + 72 = 105

Thus,

Hot dog sold = 33

Sodas Sold = 72

Answer:

0.5934% probability that a baseball player will play at an NCAA college and will also go on to be drafted by the MLB

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Playing at an NCAA college.

Event B: Being drafted by the MLB.

6.9% will play in an NCAA college

This means that $P(A) = 0.069$

8.6% of the college players will go on to be drafted by the MLB.

This means that $P(B|A) = 0.086$

What is the probability that a baseball player will play at an NCAA college and will also go on to be drafted by the MLB?

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$P(A \cap B) = P(A) \times P(B|A)$

$P(A \cap B) = 0.069*0.086 = 0.005934$

0.5934% probability that a baseball player will play at an NCAA college and will also go on to be drafted by the MLB
